I am Lily , After escaping with Shannon's money,[N 1] Tillu sets up Tillu Events, an event management company, which organizes DJs for weddings and parties. At one such party, Tillu meets Lilly Joseph and falls for her. They have a one-night stand, but Lilly disappears in the morning, leaving a note, which disappoints Tillu.

After a month of searching for Lilly, Tillu finds her at a hospital following his father's colonoscopy. Lilly reveals that she is pregnant with Tillu's child and they decide to get married. On Tillu's birthday, Lilly brings Tillu to an apartment, which Tillu recognizes it as the same apartment Radhika had brought him previously. Lilly reveals that she is looking for her missing brother Rohit, who was killed by Radhika a year prior. While looking for clues about Rohit with Lilly and Purushotham, Tillu, while trying to escape, gets kidnapped by Shannon. However, Tillu is rescued by Lilly, who kills Shannon's men.

Lilly reveals that she is not really pregnant or Rohit's sister, but is instead a secret Indian Special Forces (IFS) agent assigned to kill Sheikh Mehboob. Lilly has been tricking Tillu, who was invited to DJ at Mehboob's party in Hyderabad. She and her team have been attempting to kill Mehboob for several years, but Mehboob always avoided them with the help of an anonymous informant on Lilly’s team. She blackmails Tillu with a video of him and Radhika burying Rohit in order to get him to kill Mehboob at his party using poisoned sweets. Later, Lilly tells Tillu that she did genuinely have feelings for him even though she tricked him.

On the day of Mehboob's party, Tillu attempts to leave Hyderabad with his family to escape Lilly, but she stops him.
